A concert including alt-country singer Kathleen Edwards and rock band The Trews will hit Trafalgar Square in London, U.K., on the evening of June 30. The concert, called "Canada Rocks Trafalgar Square," is free and is being held in celebration of the Canada Day holiday on July 1.

Presented by "Alberta...A Canadian Affair," the show starts at 8.00 p.m. with an audience limited to 7,000 ticket holders. Acclaimed singer-songwriter Edwards, from Ottawa, will headline the night, performing songs from her brand new album "Asking for Flowers." Other acts on the bill include The Trews, from Nova Scotia, Jesse Cook, who incorporates jazz, Latin and world music into his performances, and extraordinary band of siblings The McDades, whose celtic-rooted music fuses jazz improvisation with global rhythms.

This free concert is being staged by the Canadian province of Alberta and leading UK tour operator Canadian Affair.

On the following evening, July 1, Canada Day hosts a second concert in the Square. The second night will include jazz pianist sensation Michael Kasehammer, folk songwriter John Wort Hannam, folk roots American musician Kim Beggs, country band Twilight Hotel and a second performance from Jesse Cook.

"Canada has such a lot to offer," says Jason Pollock, Canada Day's festival director. "For me the music gives a wonderful insight into this vibrant and fun country. That's why for the first time we've added a concert the night before Canada Day. We're celebrating the music scene with a number of different musical styles, which complement one another perfectly. And many of the performers are young and rising stars."
